Washing Your Vehicle
The best way to preserve the vehicle's finish is to keep
it clean by washing it often.
Notice:Certain cleaners contain chemicals that can
damage the emblems or nameplates on the vehicle.
Check the cleaning product label. If it states that it
should not be used on plastic parts, do not use it on
the vehicle or damage may occur and it would not
be covered by the warranty.
Do not wash the vehicle in direct sunlight. Use a car
washing soap. Do not use cleaning agents that are
petroleum based or that contain acid or abrasives, as
they can damage the paint, metal or plastic on the
vehicle. Approved cleaning products can be obtained
from your dealer/retailer. Follow all manufacturers'
directions regarding correct product usage, necessary
safety precautions and appropriate disposal of any
vehicle care product.
Rinse the vehicle well, before washing and after to
remove all cleaning agents completely. If they are
allowed to dry on the surface, they could stain.
Dry the finish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter
the vehicle. Avoid using high pressure washes closer
than 12 inches (30 cm) to the surface of the vehicle.
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions under
Washing Your Vehicle
on
page 6‑102.
Finish Care
Occasional waxing or mild polishing of the vehicle by
hand may be necessary to remove residue from the
paint finish. Approved cleaning products can be
obtained from your dealer/retailer.
If the vehicle has a basecoat/clearcoat paint finish, the
clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint finish.
6-102

Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint finish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint finish on the vehicle.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage the vehicle's finish if they remain on painted
surfaces. Wash the vehicle as soon as possible.
If necessary, use non-abrasive cleaners that are
marked safe for painted surfaces to remove foreign
matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years. To help keep the paint finish looking new, keep
the vehicle garaged or covered whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, chrome polish may be used on
chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or
chrome polish, steam or caustic soap to clean
aluminum. A coating of wax, rubbed to high polish,
is recommended for all bright metal parts.
Windshield, Backglass, and Wiper
Blades
Clean the outside of the windshield and backglass with
glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when you
clean the blades. Bugs, road grime, sap and a buildup
of vehicle wash/wax treatments may cause wiper
streaking. Replace the wiper blades if they are worn or
damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper removal
6-103

Aluminum Wheels
Notice:Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the vehicle warranty.
Use only approved cleaners on aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.
Notice: Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not be
covered by the vehicle warranty. Use chrome polish
on chrome wheels only.
The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because the surface could be damaged. Do not
use chrome polish on aluminum wheels. Notice:
Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the vehicle warranty. Never drive a
vehicle that has aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice: Using petroleum-based tire dressing
products on the vehicle may damage the paint finish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces on
the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to parts repaired or
replaced to restore corrosion protection.
Original manufacturer replacement parts will provide the
corrosion protection while maintaining the vehicle
warranty.

taken to not directly spray the transfer case output
seals. High pressure water can overcome the
seals and contaminate the transfer case fluid.
Contaminated fluid will decrease the life of the

If a Crash Occurs
Here is what to do if you are involved in a crash.
.Check to make sure that you are all right. If you
are uninjured, make sure that no one else in your
vehicle, or the other vehicle, is injured.
.If there has been an injury, call emergency
services for help. Do not leave the scene of a
crash until all matters have been taken care of.
Move your vehicle only if its position puts you in
danger or you are instructed to move it by a police
officer.
.Give only the necessary and requested information
to police and other parties involved in the crash.
Do not discuss your personal condition, mental
frame of mind, or anything unrelated to the crash.
This will help guard against post-crash legal action.
.If you need roadside assistance, call GM Roadside
Assistance. SeeRoadside Assistance Programon
page 8‑7for more information.
.If your vehicle cannot be driven, know where the
towing service will be taking it. Get a card from the
tow truck operator or write down the driver's name,
the service's name, and the phone number.
.Remove any valuables from your vehicle before
it is towed away. Make sure this includes your
insurance information and registration if you keep
these items in your vehicle.
.Gather the important information you will need from
the other driver. Things like name, address, phone
number, driver's license number, vehicle license
plate, vehicle make, model and model year,
Vehicle Identification Number (VIN), insurance
company and policy number, and a general
description of the damage to the other vehicle.
.If possible, call your insurance company from the
scene of the crash. They will walk you through the
information they will need. If they ask for a police
report, phone or go to the police department
headquarters the next day and you can get a copy
of the report for a nominal fee. In some states/
provinces with “no fault”insurance laws, a report
may not be necessary. This is especially true if
there are no injuries and both vehicles are
driveable.
.Choose a reputable collision repair facility for your
vehicle. Whether you select a dealer/retailer or a
private collision repair facility to fix the damage,
make sure you are comfortable with them.
Remember, you will have to feel comfortable with
their work for a long time.
.Once you have an estimate, read it carefully and
make sure you understand what work will be
performed on your vehicle. If you have a question,
ask for an explanation. Reputable shops welcome
this opportunity.

Managing the Vehicle Damage Repair
Process
In the event that your vehicle requires damage repairs,
GM recommends that you take an active role in its
repair. If you have a pre-determined repair facility of
choice, take your vehicle there, or have it towed there.
Specify to the facility that any required replacement
collision parts be original equipment parts, either new
Genuine GM parts or recycled original GM parts.
Remember, recycled parts will not be covered by your
GM vehicle warranty.
Insurance pays the bill for the repair, but you must live
with the repair. Depending on your policy limits, your
insurance company may initially value the repair
using aftermarket parts. Discuss this with your repair
professional, and insist on Genuine GM parts.
Remember if your vehicle is leased you may be
obligated to have the vehicle repaired with Genuine
GM parts, even if your insurance coverage does not
pay the full cost.
If another party's insurance company is paying for
the repairs, you are not obligated to accept a repair
valuation based on that insurance company's collision
policy repair limits, as you have no contractual limits
with that company. In such cases, you can have control
of the repair and parts choices as long as cost stays
within reasonable limits.
Reporting Safety Defects
Reporting Safety Defects to the
United States Government
If you believe that your vehicle has a defect which
could cause a crash or could cause injury or
death, you should immediately inform the National
Highway Traffic Safety Administration (NHTSA) in
addition to notifying General Motors.
If NHTSA receives similar complaints, it may open
an investigation, and if it finds that a safety defect
exists in a group of vehicles, it may order a recall
and remedy campaign. However, NHTSA cannot
become involved in individual problems between
you, your dealer, or General Motors.
To contact NHTSA, you may call the
Vehicle Safety Hotline toll-free at
1-888-327-4236 (TTY: 1-800-424-9153);
go tohttp://www.safercar.gov
;or write to:
Administrator, NHTSA
